Electric driving: eDRIVE
Requirements
Electric driving is possible under the following
conditions:
▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery is sufficiently
charged.▷Transmission position D or R is engaged.▷The drive system is at operating tempera‐
ture.▷The accelerator pedal is only slightly de‐
pressed.▷The driver's door is closed.
In addition, the combustion engine is switched
off during braking even below 50 mph, approx.
80 km/h or when coasting below 35 mph, ap‐
prox. 60 km/h.
In ECO PRO mode, already when coasting be‐
low 100 mph, approx. 160 km/h.
Possible cruising range
Depending on the charge of the high-voltage
battery, the vehicle can generally be driven us‐
ing electric power up to 2 miles, approx. 3.5 km.
Driving with the combustion
engine: DRIVE
The combustion engine provides the drive
power to propel the vehicle. The high-voltage
battery is charged at the same time.
Automatic start while driving
The combustion engine is automatically started
under the following conditions while driving:
▷Transmission position M/S is engaged.▷The speed does not exceed 35 mph, approx.
60 km/h.▷The high-voltage battery charge is insuffi‐
cient or it is fully charged, such as when driv‐
ing downhill.▷The required power output is increased,
such as due to the accelerator pedal position
or driving uphill.Seite 67DrivingControls67
Online Edition for Part no. 01 40 2 900 579 - 03 12 490

Automatic stopping while driving
When reducing speed, the combustion engine
is switched off when the conditions for electric
driving, refer to page 67, are met.
Assistance for the
combustion engine
The combustion engine provides the primary
drive power to move the vehicle.
The electric motor provides assistance as
needed with additional propulsive power.
ASSIST
During normal vehicle operation, the electric
motor assists the combustion engine, depend‐
ing on the situation.
eBOOST
Accelerating quickly, such as when passing, re‐
quires the maximum available power from the
electric motor. To do this, apply extra force to
the accelerator pedal.
Energy recovery: CHARGE
The hybrid system makes it possible to convert
kinetic energy into electrical power, such as
when braking. This recovered energy charges
the high voltage battery. If necessary, this stored
power is output to the electric motor.
The following conditions must be met to recover
kinetic energy:▷The vehicle is moving.▷Selector lever position D, M/S is engaged.▷The high-voltage battery is not fully
charged.
Energy recovery displays in the instrument clus‐
ter, refer to page 81.

Displays of the hybrid system
Displays in the instrument cluster
The concept
The display depends on the system's operating
condition. The following functions of the hybrid
system are shown in the instrument cluster.▷High-voltage battery charge indicator.▷Electric driving: eDRIVE.▷Acceleration boost: ASSIST and eBOOST.▷Energy recovery: CHARGE.▷Auto Start/Stop function: READY.
High-voltage battery charge indicator
Displays the state of the high-
voltage battery's charge on a
scale from 0 to 1 when drive read‐
iness is active. If the scale indi‐
cates 1, the high-voltage battery
is fully charged.
During normal vehicle operation, the high-volt‐
age battery is charged up to approx. 80 %. This
ensures optimum energy recovery when decel‐
erating or driving downhill.
Even when the scale indicates 0, the hybrid sys‐
tem is always still under high voltage.
Electric driving: eDRIVE When driving with electric power,
the power output of the electric
motor is indicated by arrows.
Depending on the position of the
accelerator pedal, up to four ar‐
rows are displayed simultaneously. The tach‐
ometer pointer stays on 0 rpm.
If all four arrows are already displayed and addi‐
tional power is required, such as for accelera‐
tion, the combustion engine switches on.
Acceleration boost: ASSIST and
eBOOST
ASSIST: the electric motor as‐
sists the combustion engine.
This is indicated by arrows in the
instrument cluster.
eBOOST: all four arrows are dis‐
played when the electric motor reaches maxi‐
mum power output.
Energy recovery: CHARGE The energy recovered is dis‐
played in the tachometer as an
arrow with the symbol +. The
high-voltage battery is charging.
Auto Start/Stop function: READY The READY display indicates
that the vehicle is ready for driv‐
ing.
